The Public Works Department and Metropolitan Planning Organization obtained the professional
engineering services of Frederic R. Harris, Inc. to conduct a Street Closure/Traffic Flow Modification
Study that was completed in July 1996.
The primary objectives of the study were to:
• Evaluate and recommend traffic control alternatives to street closures;
• Develop a uniform set of guidelines or warrants to be followed by local
municipalities, the County and the State for implementing neighborhood and
localized area traffic control; and
• Develop a standardized set of procedures to be followed by local applicants
desiring enhanced neighborhood traffic control.
A Steering Committee was assembled and periodically convened to meet with the Consultant to
provide input throughout the study process. The Steering Committee consisted of representatives
from the Florida Department of Transportation, Miami-Dade County and local municipalities; some of
whom had previous experience with citizen requests for street closures. The draft report was
developed as a series of Technical Memorandums that were reviewed by the steering committee
and later compiled to form the final report.
The Steering Committee developed standardized procedures and guidelines for use by the public,
local officials, or other private sector interests requesting traffic flow modifications that may affect
local neighborhoods as well as other roadway traffic patterns. The intent of these procedures was to
provide Miami-Dade County and municipalities with a uniform approach to facilitate government
action in response to requests to restrict local traffic access via street closures, other physical
modifications or traffic calming alternatives. These proposed procedures were also intended to
ensure that such issues are given appropriate study and timely response, and that the full range of
traffic and community impacts is considered.
The procedures addressed traffic issues in an incremental fashion with the least restrictive
measures applicable to a particular situation tested first, then monitored and supplemented,
modified or replaced with more stringent measures, if necessary. W hen non-traffic issues enter into
the decision process, the procedures weigh both the traffic and non-traffic implications of a street
closure or traffic flow modification. Although each citizen request is unique, the process applies
equally to any residential traffic control situation and provides government officials with an objective
tool to address neighborhood traffic control issues.
On May 20, 1997, the Miami-Dade County Board of County Commissioners approved Resolution
No. R-545-97 authorizing an eighteen-month pilot program to implement and evaluate traffic flow
modification/street closure study recommendations. A subsequent extension was granted under
Resolution No. R-66-00 on January 25, 2000. Since then, County staff has been using this
procedure. It has been enhanced over the span of the last twelve years and updated and revised to
appropriately address the needs of residents of Miami-Dade County in order to improve their safety
as well as their livability standards.

Phase 1: INITIAL TRAFFIC STUDY BY MIAMI-DADE COUNTY PUBLIC WORKS
1.1 All applicants, whether residing within unincorporated Miami-Dade County or a municipality,
may submit a request for a traffic flow modification(s)/street closure(s) to the Miami-Dade
County Public Works Department (PWD) in the form of a letter or complete the application
in Appendix V.
1.2 PWD will conduct the initial traffic study to confirm the applicant’s concerns and to identify
and recommend traffic calming measures. Should the request be initiated through or by a
municipality or the Florida Department of Transportation, then these agencies, at their
option, may conduct traffic studies utilizing their staff or a traffic consultant.
1.3 PWD will make the determination of whether the location(s) falls within unincorporated
Miami-Dade County or a municipality, and coordinate the review with the respective
municipality.
1.4 PWD will make the determination of whether the review from various affected entities, such
as Police, Fire, etc., is required. If review is not required, proceed to Step 1.6.
1.5 Should review be required, PWD will request the affected entities, including but not limited
to, Police, Fire, respective municipality, etc., to review the request and provide comments. If
review by any of the entities results in a denial as a result of concerns which cannot be
resolved, or if the proposed traffic flow modification(s)/street closure(s) does not meet all
criteria outlined under this process or applicable County and State laws, then the application
will be denied.
1.6. PWD will make the determination if concurrence from the required affected residents and/or
property owners is required. If concurrence is not required, proceed to Step 1.8.
Required Concurrence:
Traffic Circles: Requires 100% concurrence of affected residents and/or property
owners from four (4) corners adjacent to the proposed circles. This may be extended to
the full block should a larger representation be desired by the District Commissioner.
Traffic Flow Modifications other than Traffic Circles: Requires concurrence of two-
thirds (2/3) of the affected residents and/or property owners, who elected to vote (ballots
received). Non-voters are not counted (ballots not returned).
Municipal Jurisdictions: In lieu of concurrence from the affected residents and/ or
property owners, a municipality may pass a resolution after a public hearing requesting
PWD to consider the proposed traffic flow modification(s)/street closure(s).
1.7 PWD will mail out ballots to obtain concurrence from the affected residents and/or property
owners. Should the required concurrence be secured, PW D will proceed to the next step.
Should the affected residents and/or property owners fail to reach a consensus to implement
the proposed improvement, then the process ceases.
Traffic Flow Modification(s)/Street Closure(s) Procedure Page 5
T:\TFM\Street Closures\Procedure R4 01 09.doc
Reinitiating the balloting process: Should residents and/or property owners desire to
reinitiate the balloting process, it can be initiated after ninety (90) calendar days from the
date that ballots were opened, provided that the applicant is willing to pay the processing
and mailing cost for the ballots.
1.8 PWD will schedule the construction of temporary or permanent traffic calming device as
funds and contracts are identified.
1.9 PWD will assess the traffic impact and determine if the improvements are acceptable to the
affected area residents and/or property owners.
1.9.1 Should the determination be made by PWD staff that temporary devices have
caused adverse impact, such devices will be removed by PWD.
1.9.2 If improvements are not acceptable to affected area residents and/or property
owners:
1.9.2.1 Residents and/or property owners may request removal of temporary traffic
calming devices as per a requirement of Step 1.6. Such request must be
initiated in the form of a petition signed by 10% of the affected residents
and/or property owners. 100% of the adjacent affected residents and/or
property owners is required for the traffic circles petition. Or
1.9.2.2 Residents and/or property owners may proceed to Phase 2 procedure,
Step 2.1.
1.9.3 Improvements did not cause adverse impact and are acceptable to residents:
proceed to Step 1.10.
1.10 PWD will initiate the design.
1.11 PWD will install permanent traffic calming devices as funds and contracts are identified.
PHASE 2: TRAFFIC STUDY BY APPLICANT’S CONSULTANT
2.1 In the event that the action taken by PWD in accordance with Phase 1 procedure is
unacceptable to the municipal jurisdiction, or the affected area residents and/or property
owners, they have the option of engaging a traffic consultant, at their cost, in order to
perform an independent traffic study. Should the request be initiated through or by a
municipality or the Florida Department of Transportation, then these agencies, at their
option, may conduct traffic studies utilizing their staff or a traffic consultant.
2.2 The consultant conducts a pre-implementation traffic study to identify and confirm traffic
concerns (i.e., traffic intrusion, excessive traffic volume, speeding, traffic accidents, etc.) and
to determine if the collected traffic data meets the PWD criteria for traffic calming devices.
2.3 The consultant identifies traffic calming alternatives and generates staged alternative plans.
Traffic Flow Modification(s)/Street Closure(s) Procedure Page 6
T:\TFM\Street Closures\Procedure R4 01 09.doc
2.4 The consultant performs pre-implementation study to determine potential impacts of
proposed traffic calming devices on roadways within and outside of the study areas, and
documents findings in the form of a report.
2.5 PWD makes the determination whether the location is within a municipality or
unincorporated Miami-Dade County and coordinates the review with the respective
municipality.
2.6 PWD makes determination if the review from various affected entities, such as Police, Fire,
etc., is required.
2.7 PWD requests various affected entities, to include Police, Fire, etc., to review the request
and provide their comments.
2.8 PWD reviews comments from various entities and makes determination whether to approve
or deny the request.
2.9 PWD makes determination if concurrence from the affected residents and/or property
owners is required. If concurrence is not required, proceed to Step 2.11.
Required Concurrence from affected Residents and/or Property Owners:
Traffic Circles: Requires 100% concurrence of affected residents and/ or property owners
from four (4) corners adjacent to the proposed circles. This may be extended to the full block
should a larger representation be desired by the District Commissioner.
Traffic Flow Modifications excluding Traffic Circles: Requires concurrence of two-thirds
(2/3) of the affected residents and/or property owners, who elected to vote (ballots received).
Non-voters are not counted (ballots not returned).
Municipal Jurisdictions: In lieu of concurrence from the affected residents and/or property
owners, a municipality may pass a resolution after a public hearing requesting PWD to
consider the proposed traffic flow modification(s)/street closure(s).
2.10 Applicant obtains concurrence from the affected residents and/or property owners, if
required. In the event that the affected residents and/or property owners do not approve the
proposed improvements, return to Step 2.3.
2.11 Applicant’s contractor installs temporary traffic calming devices upon securing approvals and
permits from appropriate entities.
2.12 Applicant’s consultant conducts post-implementation study to determine if traffic calming
measures are operating at an acceptable level to the residents and/or property owners.
2.13 If the post-implementation study results, as well as the traffic calming devices are acceptable
to residents and/or property owners, the process is completed unless residents and/or
property owners desire further aesthetic enhancements. Should further aesthetic
enhancements be required, proceed to the next step. If the post-implementation study
results are unacceptable, return to Step 2.3.

1.6. Is Concurrence from the Affected Residents and/or Property Owners
Required?
PWD, depending on the proposed traffic calming devices, will determine if concurrence from
the affected residents and/or property owners is required.
Required Concurrence:
Traffic Circles: Requires 100% concurrence of affected residents and/or property
owners from four (4) corners adjacent to the proposed circles. This may be extended to
the full block should a larger representation be desired by the District Commissioner.
Traffic Flow Modifications other than Traffic Circles: Requires concurrence of two-
thirds (2/3) of the affected residents and/or property owners, who elected to vote (ballots
received). Non-voters are not counted (ballots not returned).
Municipal Jurisdictions: In lieu of concurrence from the affected residents and/or
property owners, a municipality may pass a resolution after a public hearing requesting
PWD to consider the proposed traffic flow modification(s)/street closure(s).
The affected area within unincorporated Miami-Dade County will be established by the
County’s staff. If the location falls within a municipality, the affected area will be established
by both the City’s and the County’s staff.
The affected area may include, but is not limited to, those properties where normal travel
routes to and from the affected area are to be altered by the traffic flow modification(s)/street
closure(s) and/or properties that are significantly impacted by the diverted traffic.
1.6.a If concurrence from the required affected residents and/or property owners is
required, proceed to next step.
1.6.b If concurrence from the required affected residents and/or property owners is not
required, proceed to Step 1.8.
1.7. Approval of the Plan by Homeowners
1.7.a PWD, under certain circumstances, may elect to obtain concurrence from the
affected residents and/or property owners.
1.7.b PWD will mail out ballots to obtain concurrence of the affected residents and/or
property owners.
1.7.c If the location is within a municipality, that jurisdiction, in lieu of the concurrence from
the affected residents/property owners may elect to have their elected body vote on
the proposed traffic flow modification(s)/street closure(s) after a public hearing and
may submit the resolution to PWD requesting consideration of the proposed traffic
Traffic Flow Modification(s)/Street Closure(s) Procedure Page 13
T:\TFM\Street Closures\Procedure R4 01 09.doc
flow modification(s)/street closure(s).
1.7.d If the required number of affected residents and/or property owners as per Step 1.6
do not approve the proposed improvements by PWD, then the process ceases.
1.7.e If the residents and/or property owners desire to reinitiate the process, such process
can be reinitiated after ninety (90) calendar days from the previous opening date of
the ballots. However, the applicant will be charged with the mailing and processing
cost, which will be determined on a case-by-case basis.
1.8 Implementation of Temporary Traffic Calming Measures
1.8.a If the request for traffic flow modification(s)/street closure(s) falls within
unincorporated Miami-Dade County, PWD will implement the improvements as
funding and contracts are identified.
1.8.b If the request falls within a municipality, PWD will coordinate with the municipality
for the installation of the traffic calming devices.
1.9 Evaluation of Temporary Traffic Calming Measures:
If the evaluation of the temporary devices by PWD reveals that:
1.9.a The improvements implemented by PWD did not cause an adverse impact to traffic
and are acceptable to the residents and/or property owners, proceed to Step 1.10.
1.9.b The improvements implemented by PWD are unacceptable to the residents and/or
property owners, or create unexpected operational and/or safety concerns, then:
Either the removal of temporary devices are requested through the process as per
step 1.6, or a more restrictive traffic flow modification(s)/street closure(s) may be
considered as per Phase 2, Step 2.1.
1.10 Design of Permanent Traffic Calming Devices

Traffic Flow Modification(s)/Street Closure(s) Procedure Page 14
T:\TFM\Street Closures\Procedure R4 01 09.doc
PHASE 2: TRAFFIC STUDY BY APPLICANT’S CONSULTANT
2.1. Applicant Engages a Traffic Consultant to Perform a Traffic Study
In the event that the action taken by PWD in accordance with Phase 1 procedures is
unacceptable to the municipal jurisdiction, or the residents and/or property owners, they
have the option of engaging a traffic consultant, at their cost, to conduct an independent
traffic study. Should the request be initiated through or by a municipality or the Florida
Department of Transportation, then these agencies, at their option, may conduct traffic
studies utilizing their staff or a traffic consultant.
2.1.a If the location falls within unincorporated Miami-Dade County, this study is
coordinated by PWD.
2.1.b If the location falls within a municipality, the study is coordinated by the municipality
and reviewed by the PWD.
2.2. Conduct Pre-implementation Traffic Study
The traffic consultant hired by the applicants shall perform a pre-implementation traffic
study. This study shall identify and confirm the applicant’s concerns (i.e., traffic intrusion,
excessive traffic volume, speeding, traffic accidents, etc.) and determine if the collected
traffic data meets PWD traffic calming criteria.
On a case-by-case basis, PWD, Traffic Engineering Division, may require the following
data depending on the type and complexity of the concerns:
2.2.a License Plate Survey: If the reason for the request is due to traffic intrusions, this
survey will be required for confirmation of cut-through traffic. Sampling during the
morning and afternoon peak hour periods will be considered adequate.
2.2.b Average Daily Traffic: If the reason for the request is due to an excessive amount
of traffic in the area, a sampling of twenty-four (24) will be acceptable, and forty eight
(48), or seventy-two (72) hour counts will be preferred.
2.2.c Speed Studies: If the reason for the request is due to speeding, then speed studies
are required to confirm vehicular speed. A speeding problem can be verified when
the 85th percentile speed of all vehicles is at least 10 mph greater than the posted
speed limit. A non-peak hour daytime minimum sampling of 100 vehicles will be
considered acceptable. A twenty-four (24) hour speed study utilizing traditional dual
hoses will be preferred.
2.2.d Traffic Accident History: If the reason for the request is due to traffic accidents,
then traffic accident reports for the last three (3) years are reviewed to confirm
accident history. The proposed traffic calming measure shall mitigate significant
crashes.
2.2.e Other data and/or studies as needed.
Traffic Flow Modification(s)/Street Closure(s) Procedure Page 15
T:\TFM\Street Closures\Procedure R4 01 09.doc
PWD, on a case-by-case basis, may require additional traffic data or studies if
needed.
2.2.f. If the pre-implementation study reveals that the traffic data does not support PWD
Policy for Traffic Calming Measures (Appendices I, II and III) then a final decision of
denial is rendered and the process ceases. PW D will notify the applicant of the
denial.
2.2.g If the pre-implementation study confirms that a problem exists and the traffic data
meets PWD Policy for Traffic Calming Measures (Appendices I, II and III), the
applicant may proceed to the next step.
2.3. Identify Traffic Calming Alternatives
The consultant shall adopt an area-wide systematic approach to the development of traffic
calming alternatives. This approach must work within the overall framework of the existing
roadway classification system and encourage community participation.
There are three (3) levels of traffic calming ranging from I to III to distinguish those least
restrictive (passive) traffic control measures from those that are most restrictive (active).
Among the categories, there could be many design variations unique to each device.
Ideally, the least restrictive measures to address traffic concerns should be employed first,
followed by more active and physical traffic calming devices. This incremental approach
allows a cost-effective opportunity to identify the real traffic problem, if any, and better
evaluate the impact of more restrictive measures.
Keeping the above-staged approach in mind and a handful of traffic calming alternatives
available for use on local roads, a typical request for a traffic flow modification(s)/street
closure(s) might proceed accordingly:
2.3.a The traffic consultant will assess the community’s needs.
2.3.b The consultant will generate staged alternative traffic calming plans, including design
plans for temporary and permanent traffic calming measures, for approval by PWD,
as well as cost estimates.
2.3.b.1 PWD will implement the lowest level of (Level I through Level III) traffic
control measures on a temporary basis that, in the consultant’s opinion, will
satisfy the applicant’s concerns.
2.3.b.2 Allow traffic to stabilize and reevaluate traffic patterns after six (6) months.
2.3.b.3 If Level I measures is selected and its impacts are unacceptable, then
proceed to Level II and reevaluate more restrictive traffic calming
alternatives. If Level II impacts are unacceptable, then proceed to Level III
and reevaluate.
2.3.b.4 If the impacts of Level I, II or III measure, so selected are acceptable, PWD
will implement permanent traffic control measures, as funding and
contracts are identified.
Traffic Flow Modification(s)/Street Closure(s) Procedure Page 16
T:\TFM\Street Closures\Procedure R4 01 09.doc
The following categories of traffic calming alternatives are most effective when used in
combination with each other:
LEVELS OF TRAFFIC CALMING
LEVEL I LEVEL II LEVEL III
Education
Neighborhood Speed Watch
Program
Law Enforcement
Movement Restrictions
One-Way Streets
Multi-Way Stop Control
Textured Pavement
Gateway Treatments
Border Landscaping Treatment
Chokers
Roundabouts
Traffic Circle
Speed Humps
Raised Median through
Intersections (Right Turn Only)
Mid-block Raised Islands/Medians
Semi Diverter
Diagonal Diverter
Street Closure
Speed Humps
The consultant shall also prepare a cost-estimate for the traffic calming alternatives identified
above and proceed to the next step for a pre-implementation study.
2.4. Perform Pre-implementation Study to Determine the Potential Impact of Traffic
Calming Measures on Roadways within and outside of the Study Area
The consultant shall conduct a pre-implementation study to determine the potential impact
of the proposed traffic calming devices/street closure(s), within and outside of the study area.
Depending on the type, complexity and requirements of the area in question, PWD may, on
a case-by-case basis, require analysis per Step 2.4.d and 2.4.e, which must conform to the
following criterion:
2.4.a Volume Criteria:
2.4.a.1 Future traffic volumes due to traffic diversion on any of the Residential
Local Streets may not exceed 1,500 vehicles per day (150 vehicles per
hour (VPH) during the peak hours) if a traffic flow modification(s)/street
closure is implemented. The threshold values define those limits when a
local residential street begins to lose its livability and are used for analysis
purposes only. They do not guarantee that the traffic flow modification(s)
or closure(s) will be approved.
2.4.a.2 Future traffic volumes due to traffic diversion on any of the Residential
Collector Streets may not exceed 3,000 vehicles per day (300 VPH during
the peak hours) if a traffic flow modification(s)/street closure(s) is
implemented. These threshold values define those limits when a
residential collector street begins to lose its livability and are used for
analysis purposes only. They do not guarantee that the traffic flow
modification(s) or closure(s) will be approved.
Traffic Flow Modification(s)/Street Closure(s) Procedure Page 17
T:\TFM\Street Closures\Procedure R4 01 09.doc
2.4.b Level of Service (LOS) Criteria:
2.4.b.l Future overall intersection Level of Service (LOS) must not exceed LOS
“D” or if operating at LOS "E" must not degrade to LOS "F".
2.4.b.2 The same criterion applies for an individual intersection approach within
the critical intersection approach.
2.4.b.3 If intersection or approach is already at LOS “F”, then diverted traffic
volumes must not be more than 10% of the existing traffic volumes without
diversion.
2.4.c Determine Affected Area:
The affected area may include, but is not limited to, those properties where normal
travel routes, to and from the affected area, are to be altered by the traffic flow
modification(s)/street closure(s) and/or properties that are significantly impacted by
the diverted traffic.
2.4.c.1 If the request for traffic flow modification(s)/street closure(s) falls
within unincorporated Miami-Dade County, PWD will establish affected
area boundaries on a case-by-case basis and obtain concurrence from
FDOT if their facilities are impacted.
2.4.c.2 If the request for traffic flow modification(s)/street closure(s) falls
within a municipality, both the City’s, and County’s staff will determine the
boundaries of the affected area on a case-by-case basis, and obtain
concurrence from the Florida Department of Transportation (FDOT), if their
facilities are impacted.
2.4.d Conduct Traffic Analysis within the Study Area:
For critical locations, if any, provide projection of the expected diverted traffic within
the study area. This will require the following steps:
2.4.d.1 Peak-hour turning movement counts (TMC).
2.4.d.2 Twenty-four (24), forty eight (48), or seventy-two (72), hour counts on those
streets that are proposed to be closed or modified.
2.4.d.3 Twenty-four (24), forty eight (48), or seventy-two (72) hour counts on those
streets that may be impacted by proposed traffic flow modification(s)/street
closure(s).
2.4.d.4 LOS analysis at critical locations that will be affected by redistributed traffic.
2.4.d.5 A schematic diagram for both morning and afternoon peak hours showing
existing and redistributed traffic and Average Daily Traffic (ADT).
Traffic Flow Modification(s)/Street Closure(s) Procedure Page 18
T:\TFM\Street Closures\Procedure R4 01 09.doc
2.4.e Conduct Traffic Analysis outside the Study Area
Projection of the expected diverted traffic at critical intersections, if any, adjacent to
and surrounding the affected area. Particular attention shall be paid to the impacts
on the State Highway System and County roadways, including:
2.4.e.1 Peak-hour TMC.
2.4.e.2 Queuing analysis and storage requirements at signalized
intersections.
2.4.e.3 LOS analysis at critical signalized and un-signalized existing intersections.
2.4.e.4 A schematic diagram showing the results of the TMC and ADT analyses for
critical locations.
2.4.e.5 Phasing modification requirements at existing signalized intersection.
2.4.e.6 A detailed evaluation of the impacts caused by the traffic flow
modification(s)/street closure(s) on emergency vehicle response times and
fire hydrant accessibility, as well as other services such as mail delivery,
school bus routing, transit service, trash pick-up, etc.
Each individual case w ill dictate which of the above items are
required, depending on the complexity and requirements of the study
area.
2.4.f The Report:
The consultant will document the study in the form of a report. PWD will require the
following items as part of this report:
• A drawing that shows the exact location of existing and proposed traffic flow
modification(s)/street closure(s).
• Boundary of the affected area.
• Critical intersection geometries.
• Analysis of the critical intersections and roadway links per Section 2.4.d and
2.4.e.
• Comparison of before and after LOS.
The consultant will indicate the optimum traffic calming measure from each of Levels
I, II and III, which adequately satisfies the applicant’s concern. The Level I measure
generally should be implemented first. However, depending on the severity of the
case at hand and/or unusual circumstances a higher level of measures can be
implemented. If the results are not satisfactory, then the next level measure will be
implemented until Level III is reached.
Traffic Flow Modification(s)/Street Closure(s) Procedure Page 19
T:\TFM\Street Closures\Procedure R4 01 09.doc
Any traffic study performed for traffic flow modification(s)/street closure(s) should be

traffic calming devices, unless the Director of the Public Works Department grants
an extension, or constructs permanent devices.
2.12 Conduct Post-implementation Study to Assess if the Impact of Implemented Devices
are Acceptable
Once the temporary traffic calming devices are implemented, they need to be evaluated prior
to the installation of the permanent traffic calming devices.
2.12.a Applicant requests traffic consultant to collect traffic data after the traffic pattern has
been established over a period of thirty (30) days and shall be completed within the
remaining sixty (60) days.
2.12.b Traffic consultant analyzes the data and submits reports either to PWD or the
municipality, whichever has jurisdiction.
2.13 Post-impact Analysis Results
If the study reveals that the impact of the temporary traffic control devices are unacceptable,
then the consultant shall go back to Step 2.3 to identify more restrictive traffic calming
alternatives.
If it is determined that the temporary traffic control devices are ineffective, then the request
for permanent installation shall be denied and the applicant shall direct the contractor to
remove the temporary traffic control devices at the expiration of the 90-day trial
Traffic Flow Modification(s)/Street Closure(s) Procedure Page 24

period.
2.13.a If the location falls within unincorporated Miami-Dade County, then PWD will
notify the applicant of the approval or denial of the permanent traffic flow
modification(s)/street closure(s).
2.13.b If the location falls within a municipality, and if the request is initiated by the
municipality, then PWD will notify the municipality. The municipality, in turn, will notify
the applicant of the approval or denial of the permanent traffic flow
modification(s)/street closure(s).
If the study reveals no adverse impacts and temporary devices are acceptable, then
proceed to Step 2.14.
2.14 Design of Permanent Traffic Control Devices
2.14.a If the location falls within unincorporated Miami-Dade County, then
construction plans are prepared by the applicant’s consultant and are submitted to
PWD for approval of the permanent traffic flow modifications or street closures,
including all signs and markings.
2.14.b If the location falls within a municipality, then construction plans are prepared
by the applicant’s consultant and are submitted to a municipality for approval of the
permanent traffic flow modifications or street closures, including all signs and
markings. The municipality shall then forward plans to PWD, Traffic Engineering
Division, for traffic engineering review and approval.
2.15 Installation of Permanent Traffic Calming Devices
Applicant directs private contractor(s) to install permanent closure, at their expense, upon
obtaining necessary approvals and permits from the appropriate agencies.
In situations where a traffic flow modification(s)/street closure(s) in one municipality affects
an adjacent municipality, then both municipalities shall mutually agree to such
modification(s).
Miami-Dade County has the sole discretion, subject to all applicable laws, to approve,
modify, remove, continue or deny any traffic flow modification(s)/street closure(s) request
regardless of any support or lack thereof via the petition process. The approval or denial
issued by the Director of PWD for a traffic flow modification(s)/street closure(s) is final.
